NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
135 PM EDT WED JUN 6 2012
.SHORT TERM (TONIGHT - FRIDAY)...
A LARGE MID/UPPER LVL TROUGH IS GRADUALLY PUSHING OUT OF THE EASTERN
SEABOARD AND INTO THE W ATL WITH AN ASSOCIATED SFC FRONTAL BOUNDARY
NEARLY STATIONARY ACROSS EXTREME NORTHERN FL. MEANWHILE...A
WEAKENING SFC RIDGE AXIS REMAINS TO THE SE OF THE PENINSULA AT LEAST
THROUGH FRIDAY. THIS SYNOPTIC SETUP WILL CONTINUE TO FAVOR
PREVAILING SW FLOW ACROSS THE AREA...BRINGING DEEP LAYER MOISTURE
FROM THE GULF THROUGH THE SHORT TERM.
FOR THE REST OF TODAY AND TONIGHT...SCATTERED SHOWERS WITH
OCCASIONAL THUNDER WILL CONTINUE THROUGH THE EVENING HOURS WITH THE
SW FLOW DRAGGING ABUNDANT MOISTURE FROM AN AREA OF DISTURBED WEATHER
OVER THE SOUTHERN/CENTRAL GULF WATERS. WILL CONTINUE TO CARRY 40-50
POPS TONIGHT...THEN INCREASING TO 60-70 POPS ON THU MAINLY IN THE
AFTERNOON HOURS WHEN THE DEEPER MOISTURE IS EXPECTED. WITH THE
ROBUST SW FLOW IN PLACE...RISK FOR RIP CURRENT ALONG AREA BEACHES
CONTINUE UNTIL 9 PM THIS EVENING. ALWAYS HEED THE WARNINGS AND
POSTED REGULATIONS BEFORE GOING INTO THE WATER...AND TRY TO SWIM IN
BEACHES WITH LIFEGUARDS ON DUTY.
MODEL GUIDANCE SUGGESTS THAT THE FRONTAL BOUNDARY COULD LINGER
FURTHER SOUTH...BUT NOT MOVING ACROSS THE STATE ENTIRELY...THUS
KEEPING CHANCES OF RAIN IN THE 30-60 PERCENT RANGE NORTH-TO-SOUTH ON
FRI.
IN TERMS OF IMPACTS...GREATEST THREAT WILL BE POTENTIAL FOR HEAVY
DOWNPOURS AND LOCALIZED FLOODING...ESPECIALLY ACROSS THE TAMPA BAY

TUESDAY. ALOFT...THE SHORTWAVE WILL GRADUALLY SHIFT EAST ACROSS
THE NORTHERN GULF THROUGH THE PERIOD WITH VORT MAXES MOVING OVER
THE AREA THROUGH THE WEEKEND AND EARLY NEXT WEEK. THE UPPER ENERGY
COMBINED WITH THE MOIST ENVIRONMENT WILL ALLOW FOR SCATTERED

THE UPPER 80S TO LOWER 90S EACH DAY.
